The objective of this study was to use phylogeny-based and community-based analyses to compare the community composition of Agaricomycetes among four different agricultural treatments at the Kellogg Biological Station Long Term Ecological Research (KBS LTER) site. A phylogenetic tree that included 591 ribosomal DNA sequences previously obtained from KBS LTER documented the composition of Agaricomycete communities in each treatment. Sequences from KBS LTER were placed into 472 OTUs (putatively species-level operational taxonomic units defined by 99% or greater sequence similarity) and these were dominated by the Agaricales (with 330 OTUs), Cantharellales (39 OTUs), Hymenochaetales (29 OTUs), and Polyporales (23 OTUs). …

Some scholars argue that different modes of mobility produce different ways of knowing the world. Automobiles and their associated physical and social constructs are accused by some of alienating their drivers and those outside the car, whereas others see the human-machine hybrids they create as inherently connecting. Bicycling and walking are often seen as providing a more connected experience of places traversed, though the “automobilization” of these environments may conversely alienate cyclists and pedestrians through a host of social and environmental injustices, both local and global. Little empirical research has attended to this debate. This dissertation research is founded upon …
